I am running the latest 8.4.2 Elastic stack.
If I go to stack monitoring (/app/monitoring#/logstash/pipelines?_g=(cluster_uuid:xxxxxx), I get an overview of my pipelines.
If I click on the only pipeline that is listed, I get an error message. Changing the time window does not make any difference.
Pipeline documents for [main @ xxxxxxxxxxxx] not found in the selected time range for cluster [xxxxxxx]. HTTP 404
Bug? This has been working before, but has also failed sometimes in previous releases.
